摘要:

在光子计数机制下进行光学测量是现代物理学中反复出现的挑战,也是开发弱侵入探针的保证。在这里,我们研究这个想法的混合纳米光学机械系统组成的纳米线杂交到一个单一的氮空位(NV)缺陷。纳米谐振器的振动赋予量子发射器空间自由度,并且光子发射事件现在可以在空间和时间上变化。我们研究了纳米运动是如何被编码在探测到的光子统计上的,并探索了它们的时空相关特性。这允许当每个振荡周期检测不到一个光子时,在光子计数机制中以前所未有的低光强度定量测量纳米机械振荡器的振动,其中标准检测器是暗噪声限制的。这些结果具有探测弱相互作用的纳米谐振器,低温实验和调查单一移动标记的影响。

英文摘要:

Optically measuring in the photon counting regime is a recurrent challenge in modern physics and a guarantee to develop weakly invasive probes. Here we investigate this idea on a hybrid nano-optomechanical system composed of a nanowire hybridized to a single Nitrogen-Vacancy (NV) defect. The vibrations of the nanoresonator grant a spatial degree of freedom to the quantum emitter and the photon emission event can now vary in space and time. We investigate how the nanomotion is encoded on the detected photon statistics and explore their spatio-temporal correlation properties. This allows a quantitative measurement of the vibrations of the nanomechanical oscillator at unprecedentedly low light intensities in the photon counting regime when less than one photon is detected per oscillation period, where standard detectors are dark-noise-limited. These results have implications for probing weakly interacting nanoresonators, for low temperature experiments and for investigating single moving markers.
